To LZZ whom it may concern:

Be it known that we, WILLIAM WALLACE KETLER vand EDWARD BRITTON, citizens ot' the United States, residing at North Lawrence, in the county of Stark and State of Ohio, have invented a new and useful Claw- Bar, of which the following is a speciiication.

This invention relates to claw-bars, and has for its object to provide an improved device of this character which is constructed and arranged to facilitate the engagement of the claw with the spike or other fastening to be withdrawn.

lt is furthermore designed to have the base or fulcrum-block, the claw, and the operating-lever formed in separate members, so as to be readily replaced in the event of wear or breakage.

A further. object is to provide for seating the claw into snug engagement with the spike to be withdrawnv by the initial movement of the lever and also to secure a powerful opera-V tion of the lever and a comparatively long range of action for the claw. p l'Vith these and other objects in view the present invention consists in thecombination` and arrangement of parts, as will be herein-'1 after more fully described, shown in the accompanyin g drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion,n

size, and minor details may be made within the scope of the claims without departing from the spirit or sacriiicing any of the advantages of the invention.

In the drawings,-Figure l isa perspective View of a claw-barembodying the present invention. Fig.Y 2 is a side elevation thereof, parts'being broken away to show the connections between the several members of the device. Fig. 3 is an inverted detail perspective view ofthe forked end of the operatinglever.

Like charactersy of reference designate corresponding parts throughout the several figures of the drawings. I

In carrying out the present invention there is provided a base or fulcrum-block i, which` able pivot-pin 6, piercing said ears and also extending through a longitudinal slot 7, formed in the shank.

For the operation of the claw, there is provided a lever 8, which hasits lower end enlarged and forked, as at 9, so as to straddle the head of the claw, to whichit is pivotally connected, as indicated at l0. The under side of the lever is provided with a longitudinal socket or recess 11, which is located at the lower or forked end thereof and is designed for the reception of the upper side of the clawshank, softhat the opposite ymembers of the fork may lie in engagementwith the front upper edge of the fulcrum-block inthe initial application of theAv device to a spike.

In the operation of` the device the claw is applied to a spike as indicated` in Fig. 2 of the drawings, the lever being in a' substantially vertical position and the claw at its rear limit, whereby the opposite members of the forked portion of thelever lie against the adjacent front side of the fulcrum-block. By forcing the upper end of the lever rearwardly fupon its engagement with the block asa fulcrum-point the claw is forced forwardly, so

as to snugly engage the block, after which the claw is swung upwardly by a further movement of the lever, and the fulcrumpoint is finally changed to the pivotal connection of the claw with the fulcrum-block, whereby the initial movement of the lever exerts a powerful lifting force and a comparatively wide range of movement is given to the claw. Y Y

It will of course be understood that the two pivotal connections are removable, so as to permit of any of the parts being replaced should they become damaged or broken and also to facilitate storage and transportation of the device.

Having thus described our invention, what we claim as new, and desire to secure by Leta ters Patent, is-

IOO

I. A claw-bar, comprising afulcrum-block, a claw pivotally connected thereto, and an operating-lever pivotally connected to the claw and having an intermediate fulcrum engagement with the block above the pivotal connection between the claw and the lever.

2. A claw-bar, comprisingafulcrum-block, a claw pivotally connected thereto by means which permit of the longitudinal extension of the claw therefrom, and an operating-lever pivotally connected to the claw and adapted to have an intermediate fulcrum engagement with the block.

3. A claw-bar, comprising a fulcrum-block, a claw having an endwise-slidable and pivotal connection with the block, and an operating-lever pivotally connected to the forward portion of the claw and having its intermediate portion constructed to bear against the block as a fulcrum-snpport.

4. A claw-bar, comprising a fulcrum-block, a slotted claw, a pivot-pin piercing the block and the slotted portion of the claw, and an operating-lever pivotally connected to the claw and having its intermediate portion constructed to have a fulcrum-bearing upon the block.

5. Aclaw-bar, comprising a fnlcrum-block having opposite npstanding bearing-ears, a claw having a longitudinal-slotted shank portion received between the ears, a pivot-pin piercing the ears and passing through the slot of the shank, and a forked operating-lever straddling the claw and pivotally connected thereto, the intermediate portion of the lever being constructed to have a fulcrumbearing upon the ears of the block.

6. A claw-bar, comprising a fulcrum-block, a claw, an operating-lever, and connecting means between these parts to shift the initial fnlcrum-bearing of the lever upon the block to the connection between the claw and the block.

7. Aclaw-bar, comprising a fulcrum-block, a claw pivotally connected thereto, and an operating-lever having its lower end pivotally connected to the claw below the pivotal connection between the claw and the fulcrumblock, the latter having aportion rising above the pivotal connection between the claw and the leverand located in the path of the rearward movement of the lever to form a fnlcrum-bearing thereof.

8. A claw-bar, comprising a fulcrum-block, a claw pivotally and adjustably connected thereto, and an operating-lever pivotally connected to the claw between the operative end of the latter and its pivotal connection with the block.

In testimony that we claim the foregoing as our own we have hereto affixed our sign atures in the presence of two witnesses.
